Summary
This narrative review by Traka and Mithen, published in Molecular Nutrition & Food Research, synthesises the evidence on the biological activity of glucosinolates — secondary metabolites found principally in Brassica vegetables — and their breakdown products, particularly isothiocyanates such as sulforaphane. The paper likely covers metabolic pathways, bioavailability, and proposed mechanisms of action including modulation of detoxification enzymes and anti-inflammatory pathways. It represents a contribution to understanding how dietary exposure to Brassica-derived compounds may influence risk of cancer and other chronic conditions.
UK applicability
Directly applicable to UK dietary guidance and public health policy, given that Brassica vegetables such as broccoli, cabbage, and Brussels sprouts are widely grown and consumed in the UK; Mithen's group at the Institute of Food Research (now Quadram Institute, Norwich) has been central to UK-based Brassica breeding programmes aimed at enhancing glucosinolate content for health benefit.
Key measures
Glucosinolate content and profiles in Brassica vegetables; isothiocyanate bioavailability; cancer risk associations; phase II enzyme induction; epidemiological associations with chronic disease
Outcomes reported
The review examines the metabolism, bioavailability, and health-protective mechanisms of glucosinolates and their hydrolysis products, particularly isothiocyanates, with a focus on cancer chemoprevention and other chronic disease outcomes. It likely synthesises epidemiological, in vitro, and in vivo evidence linking Brassica vegetable consumption to reduced disease risk.
